Abstract N-(3, 4-Dihydroxyphenethyl)-3, 5-dinitrobenzamide modified-multiwall carbon
nanotubes paste electrode was fabricated and used as an electrocatalyst for the oxidation of
ascorbic acid (AA), acetaminophen (AC), and tryptophan (TP) at pH 7.0. In a mixture
containing AA, AC, and TP, the separation potentials were large enough to determine those
compounds individually and simultaneously. The peak currents obtained were found to be
linearly dependent on AA, AC, and TP concentrations in the ranges of 0.03–70, 0.6–452, ...
